Top Baby Names of 1915

What the Data Says About 1915

The Social Security Administration's national 1915 file shows 1,262,190 births concentrated in the top 100 boy and top 100 girl names, the segment of U.S. baby-name data released to the public for that year. The #1 boy name of 1915 was John, with 47,576 births registered nationally. The #1 girl name of 1915 was Mary, with 58,187 births nationally. The top 100 boys captured 608,052 births compared with 654,138 for the top 100 girls — consistent with the historical SSA pattern in which a smaller pool of boy names dominates a larger share of annual births while girl names are more evenly distributed.

1915 sits within a specific era of U.S. naming trends. Pre-1940 years are dominated by traditional biblical and English names — John, William, Mary, and Helen consistently occupy the top ranks, and the top 10 names account for a much larger share of all births than in later decades. John and Mary leading 1915 fits this broader cultural signature.

These rankings come directly from Social Security Administration card applications and represent approximately 96% of all U.S. births in 1915. Names with fewer than five occurrences nationally in 1915 are excluded from SSA's public file to protect privacy, meaning the true number of unique names given in 1915 is significantly larger than any public top-100 list can show. Each spelling variation is counted separately — Sophia and Sofia, Aiden and Ayden — so rankings reflect only the specific spelling filed on the SS card, not combined name pools.
